Angewandte Chemie, EarlyView.This work presents the synthesis, characterization, and reactivity of an iridium distannylidyne as the first heavy transition metal ditetrylidyne. Characterized by its short Ir─Sn bonds and linear bonding angles at the tin atoms, this compound displays versatile reactivity toward carbon dioxide and trimethylsilyl azide.

An algorithm for computing Schubert varieties of best fit with applications
Frontiers in Artificial Intelligence, 2023 We propose the geometric framework of the Schubert variety as a tool for representing a collection of subspaces of a fixed vector space. Specifically, given a collection of l-dimensional subspaces V1, …, Vr of ℝn, represented as the column spaces of ...

Angewandte Chemie, EarlyView.One catalyst for two products: CO acts as a molecular trigger for adaptive alkyne hydrogenation using supported Pd nanoparticles. The catalyst reversibly switches between the formation of alkanes under H2 and Z‐alkenes under H2/CO for 37 structurally diverse alkynes.

On Schubert calculus in elliptic cohomology [PDF]
Discrete Mathematics & Theoretical Computer Science, 2015 An important combinatorial result in equivariant cohomology and $K$-theory Schubert calculus is represented by the formulas of Billey and Graham-Willems for the localization of Schubert classes at torus fixed points.

Current Musicology, 2000 A constant of Schubert reception has been the image of an unintellectual composer. From the early stories of songs gushing from his pen at near-performance tempo, to the Biedermeier Liederfiirst, and the shy but good-natured tippler of Dreimiiderlhaus ...

Graded Metallopolymer Structures with Shape‐Memory Abilities via DLP‐Based 3D‐Printing
Advanced Functional Materials, EarlyView.This study presents the digital light processing (DLP) based 3D printing of graded metallopolymers featuring shape‐memory abilities. The permanent shape can be recovered in two distinct steps with excellent rates. The obtained graded prints range from simple rod‐like structures to complex hollow materials.

Advanced Materials, EarlyView.A scalable bottom‐up CVD methodology, based on liquid transition metal salt precursors, is presented for the controlled growth of two high‐quality MoSe2–WSe2 heterostructures (HSs): purely lateral (HS I) and hybrid lateral/vertical (HS II), by simply adjusting precursor concentration.

Schubert polynomials and $k$-Schur functions (Extended abstract) [PDF]
Discrete Mathematics & Theoretical Computer Science, 2013 The main purpose of this paper is to show that the multiplication of a Schubert polynomial of finite type $A$ by a Schur function can be understood from the multiplication in the space of dual $k$-Schur functions. Using earlier work by the second author,

Dynamic Fluorescence Modulation via Light‐Driven Competitive Protonation
Advanced Optical Materials, EarlyView.A two‐component molecular system demonstrates reversible, light‐driven fluorescence write–erase cycling and thermal imaging. Illumination of a merocyanine photoacid transfers a proton to a highly efficient fluorescent pyridinium dye, switching its emission color; thermal relaxation reverses the process in the dark.
